Question

can someone please help me answer this question? I will fan and give a medal!! I could really use some help...
Question~
Graph the following systems. Draw one line in yellow and one line in blue. Indicate the solution to the system ON the GRAPH.
x - y = 0
3x + y = -4

Answer 1

you can just solve for y in both equations so the first equation would just be y = x and for the second equation you would subtract y to both sides and then add 4 to both sides giving you -y = 3x + 4 and then you would multiply both sides by -1 leaving you with y = -3x - 4

Answer 2

I'm not sure what you mean... Could you put it on a graph for me? Please?

Answer 3

ya 1 sec

Answer 4

thank you sooo much!!!!

Answer 5

it says the blue line should have a negative slope of 3 and should cross the y axis at -4.
(im kinda new to this so the graph was not that great.)

Answer 6

Thank you sooo much!! you're awesome!!

Answer 7

no problem
